The present invention relates to a novel use of N-(4-isopropylphenyl)-5-amino-isoindoline for diagnosing Alzheimer's disease and quantifying amyloid in the brain.

The present invention relates to labeled compounds suitable for positron emission tomography (PET) imaging and/or fluorescence imaging such as near-infrared fluorescence imaging (NIRF). The invention further relates to the use of these compounds for carrying out PET scans. imaging calcium sensing receptor (CSR)-positive organs. excising parathyroid tissue. protecting parathyroid tissue during thyroid surgery, and treating disorder(s) of a CSR-positive tissue in a subject.

There is provided a central nervous system labelling composition for intranasal administration for the purpose of labelling the central nervous system from the olfactory epithelium by way of the olfactory bulb and by means of intranasal administration. Additionally, there is provided a method of non-invasively labelling the central nervous system by way of an administration route that entails little transferability to the entire body. Furthermore, there is provided a screening method using a central nervous system labelling composition for intranasal administration. A central nervous system labelling composition for intranasal administration is characterized by labelling the central nervous system from the olfactory epithelium by way of the olfactory bulb and by means of intranasal administration and by containing at least one compound expressed either by the general formula (1) or the general formula (2) shown below as effective component: ##STR00001##

A method includes administering to a subject (i) a pharmacological agent that binds to receptors in a subject, and (ii) a radiotracer to alter a functional state and occupancy of the receptors in the subject. The method also includes acquiring imaging data of brain tissue in the subject comprising the receptors. The imaging data include positron emission tomography (PET) imaging data and functional magnetic resonance (fMR) imaging data. The method further includes calculating (i) a dynamic response of the functional state to the pharmacological agent and the radiotracer based on the fMR imaging data, and (ii) a dynamic response of the receptor occupancy to the pharmacological agent and the radiotracer based on the PET imaging data.

The compounds of the invention are modulators of cannabinoid receptors CB1 or CB2. The compounds can be used for the prevention or treatment of, e.g., pain, cancer, skin diseases, weight-associated disorders, chemical addictions, psychiatric disorders, neurodegenerative disorders, bone diseases, and inflammatory diseases. The compounds of the invention can further be used to study these diseases and disorders, as well as cannabinoid receptor biology, by coupling the compounds to, e.g., imaging agents.

The present invention provides for heptamethine cyanine dyes that possess both nuclear and near-infrared imaging capabilities. These dyes can be used for imaging, targeting and detecting tumors in patients.

The present disclosure relates to combination treatments for cancer. Specifically, the present disclosures relates to combination treatment of neuroendocrine tumors with an inhibitor of estrogen signaling or a retinoid, and radiation therapy or targeted radionuclide therapy.

The present invention relates to a novel use of N-(4-isopropylphenyl)-5-amino-isoindoline for diagnosing Alzheimer's disease and quantifying amyloid in the brain.

The present invention relates to the use of arylalkanolamine compounds with sigma-1 receptor antagonist activity. In particular, the said arylalkanolamine compounds are useful in the treatment of conditions selected from the abuse of psychotropic substances such as cocaine or amphetamines, pain and cancer.

Various compositions and methods for Quasi-Amadori products and derivatives thereof are contemplated in which a halogenated carbohydrate is reacted with a primary amino group of an affinity ligand. In especially preferred aspects, the Quasi-Amadori product is formed from 2-fluorodeoxyglucose and an affinity moiety that preferentially or selectively binds to a neural cell or neural structure. Where contemplated compounds include .sup.18F, PET imaging using compounds presented herein is especially preferred.
